One object of the inwhich the entire heater may be supported vention is to provide a compact and durable from above. apparatus for drying sand and to embody E E are hangers attached preferably one in such an apparatus means for drying the to each end of a loop of the central heating sand rapidly. Another object is to embody element B and each hooked over a portion 60 in such an apparatus means for heating the of the coil A. sand throughout its mass. Another object F F are intermediate stiffenino' and is to provide means for vibrating and shaltstrengthening means attached to the coil A, ing the mass of sand during the time of located preferably one on each side of the drying.

The vibratory mechanism Which is applied to vibrate the device causes motion of the device, but does not move the device. as a Whole away from its position.

The use and operation of my invention are as follows:

The heater is normally mounted Within a building or shelter and is preferably supported from above. Steam is turned into it and it is made hot. is poured into the open flaring top of the heater and passes dovvn in contact With the'- coils. In the usual practice the sand Will be put in until the heater is substantially full, and as it runs out other sand will be put in, mali-ing the heater operate in a substantially continuous process. The sand Will be heated by contact with the coil proper andl With the interior heating'v element.- rIhe heater is vibrated by operation of the steam hammer and thus the heating elements with Which the sand is in contact are' in a state of vibrationl and the sand is to some extent agitated and stirred upi and lumps are thus brokenup and the' sandy is separated and shaken and is in effect stirred so that suhstantia'lly allel the sand comes in contact with the heating element. I u y As the sand' is hrolen up it becomes small enough to flovv through the cracks between the pipes of the coiland itpasses outward and is discharged Afrom the drier and re'- ceived inV any suitable receptaclev and convey'ed avvayl Y The vibrating hammer serves to expedite the' tl'oiv of sandy through andk out of the drier, in addition'- toitsl function above described of tending? to break up' the sand and bring it in contact With the heating elements,

In order to permit removalsof accumulated material such as' dirt and other impurities, the removable bottoni plates" have beenr provided. When such material accumulates these plates may be'vremove'd from bottom of the drier and the vlarge particles discharged from' the bottom, or in case they are too large tobe discharged through the open bottom, they may ofcourse be either broken up by tools" through' the open bottom or removed tliroughfthe'top of the drier. Usually when the bottom slides are tobe removed, the drier is emptied of sand as nearly as possible before making the removal.
